Moringa oleifera Lam. (Moringaceae) is one of the most versatile plants cultivated all over the world. It is popular in Nigerian due to its nutritional and medicinal values; almost every part of the plant can be used for food, medication or industrial purposes. They are claimed to treat different ailments in the indigenous system of medicine. The nutritional and medicinal values are due to the presence or absence of certain primary and secondary metabolites synthesized by the plant. Climatic condition, soil composition and other factors are reported to influence the synthesis of these metabolites. Consequently, the nutritional and phytochemical contents of the plant may vary from place to place. Several reports on the qualitative phytochemical analysis of Moringa oleifera leaves from different climatic zones in Nigeria were collated and evaluated. The data revealed the presence of alkaloids, flavonoids, saponins, steroids, tannins and phenolics in Moringa oleifera leaves from all the climatic zones. However, some phytochemicals present in Moringa oleifera leaves from one zone were absent or not detected in the leaves from another zone and this could be attributed to the climatic influence and the solvents used for extraction.
